Well I personally think that the Impala is the sexier of the bunch. however it does weigh a little more. I would have to say that if you have a little more than 30K in your budget and some time, then wait for the G8 , w/ 362 HP / 392 tq an aprox 0 - 60 in 5.3 sec and qtr mile ib an expected 14.1, it's sure to please the driver. It would also be safe to say that there are going to be some decent upgrades since it is supposed to use the same engine as the NEW Camaro. ( drool ) . I personally opted for the Impala, I love it but there are minimal upgrades available. Other than that, It's an awesome car.
